This 3-season sleeping mat is optimized for maximum insulation and comfort, with a width that fits modern tents. The mat features loops to connect an Air Pillow for added length protection and connection loops on each side to join multiple mats and avoid cold gaps. The stuff sack doubles as a pump bag, allowing for easy inflation with one hand and in tight spaces. Additionally, the mat has slightly higher channels on the sides to keep you on the mat throughout the night.
